Scrapy lets you straightforwardly pull data out of the web. It helps you retry if the site is down, extract content from pages using CSS selectors (or XPath), and cover your code with tests. It downloads asynchronously with high performance. You program to a simple model, and it's good for web APIs, too. If you use requests, mechanize, or celery for HTTP, you should probably switch to scrapy.

Our culture's default assumption is that everybody should always be striving for perfection -- settling for anything less is seen as a regrettable compromise. This is wrong in most software development situations: focus instead on keeping the software simple, just "good enough", launch it early, and iteratively improve, enhance, and re-factor it. This is how software success is achieved!

C++ brought exceptions to mainstream programming; Java goes further with checked exceptions. But are exceptions the one way to report all errors? Scala and Go suggest there is more than one kind of error, so there should be more than one kind of error reporting, and different responses to errors. I’ll show the Scala and Go approaches to the error problem, and how to apply this to Python.

How do you grow the next generation of hackers? As our community gets older, we are making little humans, and we have an excellent opportunity as parents to indoctrinate them with seditious ideas like "it's better to share", and "if you don't like the way things are, change them".
Here's one parent's story of toys and activities for kids from 3 to 10 to grow a new hacker generation.
